You need to remember that when creating a map, especially your first map, you should accomodate to the mod and existing gameplay mechanics that come with it, not the other way around. That means your map supposed to work within the mod without any changes, especially to basic mechanics like SL spawn etc. Otherwise we are not talking about mapping here anymore, but about creating a minimod, so keep it simple.
Also note, that changing gameplay mechanics to YOUR LIKINGS, but only map side is probably not the best idea because, gameplay for the most part is, and should always be global (affect mod as a whole), and due to that fact, be well known and easily understandable by ALL players in game. Any deviation from that will be unclear, confusing or frustrating at least to some people and you don't want that. Not to mention that it is a simple matter of taste. You like when people play smart, others like to just run n' gun. A good map should satisfy them all.
